SAPFIR-Structures

  • Updatable soil model may be attached to 3D model of the structure. In SAPFIR program it is possible to make mutual arrangement between building model and the soil. Soil model with the snap is automatically transferred to VISOR-SAPR module. The user could temporarily hide certain soil layers, make imaginary 'elevation view' of soil owing to section box extents. Soil model may be updated with account of modifications made in the SOIL system; the specified snap remains the same.

  • The user could manage the design parameters of steel structures directly in SAPFIR environment. It is possible to define classes for steel, additional design parameters for columns and beams, selection limitations for sections. With parametric filter, the user could select elements of steel structures by certain parameters. When data is transferred to VISOR-SAPR module, the program automatically generates structural elements and false deflection fixities.

  • New tool to define intermediate levels in storeys. It is possible to define the snap for objects (walls, slabs, columns, beams, roofs and rooms) to levels (top of storey, bottom of storey, intermediate). Levels may be displayed at section elevations. When you edit certain level, the program automatically modifies levels of objects that refer to this level.

  • New object 'Inclined slab' is introduced.
  • Offsets are available for beams and columns. Offsets may be generated to the level of storey top, storey bottom, intermediate levels. Moreover, it is possible to generate offsets to selected object: for beams to slabs and conventional planes (hatching), for columns to walls.

  • Input data may be defined for wind analysis with pulsation.
  • Option to define snaps of loads to selected object. The load is referred to the level where the object is located. When the object level is modified, the load is automatically moved as well.

  • New mode for selection of line segments to move them together or to assign boundary conditions.
  • New tool that enables the user to check the integrity of design model visually. On design model you will see contour plots of distances to supports and indication for elements with no support.

Design of RC structures

  • Types of pilot reinforcement (PR) are automatically generated and then assigned to elements of design model according to design procedures for slabs, walls, columns, beams in Design of RC structures module. In this module there is a system of user-defined settings that enables the user to define and assign the types of pilot reinforcement (PR). These settings are applied by default.

SAPFIR-Generator

  • When *.spf file is opened, if the model contains import nodes DXF, then the program checks whether *.dxf files are available at the specified paths. In case such files are not found, the program displays message that *.dxf files are not found and import nodes are frozen. The warning that there is no related *.dxf files is not provided any more.
  • New node is introduced: 'Enhanced generation of storeys by specified levels'.

  • Enhanced node for cutting openings in slabs. It results in less time necessary for work and considerable reduction of file size if this node is used inefficiently.



Plugin for Grasshopper

  • For our standard nodes (wall, slab, column, beam, pile, prism, surface, points, lines) it is possible to activate the 'Properties of SAPFIR object' dialog box within the Grasshopper environment.
